LUBRlCATO R.

SPECIFICATION forming part of Letters Patent No. 305,608, datedSeptember 23, 1884.

Application filed August 1. 1884.

To all whom it may concern.-

Be it known that I, AUGUST Lorz, of the city of San J os, in the countyof Santa Clara and State of California, have invented an Improvement inLubricators; and I hereby declare the following tobe a full, clear, andexact description thereof.

My invention relates to a new and useful lubricator of that class inwhich the flow of feed of the lubricating material is governed by themovement of machinery which it effects.

My invent-ion consists in a plug or cylinder adapted to be rotated bythe power-shaft, and having a receptacle or chamber in its surface bywhich the rotation of the plug is brought intor'elation with thedischarge of the oilcup to receive its oil, which is thence carried downand discharged into a suitable opening or passage upon the part to belubricated.

The object of my invention is to provide a simple and effectiveautomatically-operating lubricator.

Referring to the accompanying drawings for a more complete explanationof my inven tion, Figure 1 is a vertical section of my lubricator. Fig.2 is a vertical section, showing the plug and gear in elevation. Fig. 3is an elevation.

A is an oil-cup having a discharge, a, at its bottom.

B is a casting or shell, in which is mounted a tapering cylindricalplug, 0, having a chamber or recess, 0, in its surface, which is adaptedto be brought into communication with the discharge a of the oil-cup Theshell B is provided with a discharge, 1), which may be supposed to be incommunication with thatpart of the machinery which is to be lubricated.

D is an air-passage passing through the shell B and opening against thecylindrical plug, its upper end extending upwardly and- (No model.)

of oil. Continued rotation thence carries the chamber around, with itscharge of oil, until it comes into communication with thedischarge-passage b, directly below, into which it deposits the oil,thence passing up on the other side of the shell to the air-passage D,

by which the pressure is relieved preparatory to receiving a new chargeof oil from the discharge a. It will thus be seen that the operation ofthe lubricator, depending upon, the power transmitted from the machineryitself, is automatic, and a steady quantity of oil is deposited at eachrevolution of the plug. The device is simple and economical, and isadapted to be readily attached to any portion of the machinery.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A lubricator consisting of a cup, A, having passage a, the casting orshell B, having passage 1), and the rotating cylinder or plug (J,mounted in said casting and having a chamber or recess, 0, adapted to bebrought into communication with the passage a of the oilcup and thepassage 1) of the shell B, substanstantially as herein described.

2. In a lubricator consisting of a cup, A, having a discharge-passage,a, a casting or shell, B, having a discharge-passage, b, an airpassage,D, passing into said shell, and a r0- tating plug or cylinder, 0, havinga chamber or recess, 0, adapted to be brought into COIllmunication withthe discharge-passage a of the cup, the discharge-passage b of theshell, and the air-passage D, substantially as herein described. i

3. The oil-cup A, having passage to. and the shell or casting B, havingdischarge-passage b, in combination with the cylinder or plug 0, havinga chamber or recess, a, and the means by which said cylinder or plug isrotated in order to bring its chamber into communication with thepassages to and 1), consisting of the worm-gear F, upon the axis of saidplug, and the worm e, on the power-shaft E of the machinery to which thelubricator is attached, substantially as herein described.

In witness whereof I have hereunto set my
